Artificial ghosts were created by scientists in Switzerland using a robot device as part of a lab experiment.
The experiment focused on the sensory-motor signals of the brain and found that the illusion of a ghostly presence was due to a programmed delay between the brain’s processing of the body’s movements and its sense of self.
Are ghosts merely an illusion of the mind? We look at the experiment, in this Lip News clip with Elliot Hill and Mark Sovel.
Professor Olaf Blanke, who led a team at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland, says the research has given up the ghost to science.
He said: ‘Our experiment induced the sensation of a foreign presence in the laboratory for the first time. It shows that it can arise under normal conditions, simply through conflicting sensory-motor signals.
